SPECIFICATION forming part of Letters Patent No. 325,883, dated September 8, 1885.

Application filed February [4, 1885. (No specimens.)

To all whom it may concern.-

Be it known that I, ISAAC P. WENDELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Composition of Matter, of which the following is a specification.

The object of my invention is to provide an inexpensive material having the proper hardness and durability for the manufacture of axle or journal bearings, packings for pistons, and like articles,

My invention consists in a compound composed of asbestus, lithar e, and silicate of soda. The asbmving first been reduced to a condition of fiber or powder, and the lithargc,

. in the form of a powder, are well mixed with liquid silicate of soda, EQLlQdiHtO the desired form, and dried by artificial or p atpral heat The proportions o'i'fie fiaterials above named which I have found to produce a good article are, one pound of asbestus, one-half pound oflit harge and three-quarters of a pound of liguid silicate of soda, or the correspondingainounto crysta ize silicateofsoda, or the corresponding amounto ot er equivalentindura-tin material. These proportions, however, may be varied, and other oxides or compounds of lead may be used in the place of litharge, without departing from my invention.

Having thus described my invention, I claim A composition, of matter consisting of asbestus, litharge, and silicate of soda, substantially as set forth.

In testimony whereof I have hereunto signed my name this '3d day of February, A. D. 1885.

ISAAC P. WENDELL.
